The actual texture size to be applied to the polygon being drawn is the product of the base tile size and the size of the indirect map. The <A href="../TexCoordGen/GXSetTexCoordScaleManually.html"><CODE>GXSetTexCoordScaleManually</CODE></A> function must be called to set the appropriate texture coordinate scale. The <A href="GXSetIndTexCoordScale.html"><CODE>GXSetIndTexCoordScale</CODE></A> function can also be used to use the same texture coordinates for the indirect stage as for the regular TEV stage.</P> 167 168<h2>See Also</h2> 169<P class="reference"> 170<A href="GXSetTevIndirect.html">GXSetTevIndirect</A>, 171<A href="../TexCoordGen/GXSetTexCoordScaleManually.html">GXSetTexCoordScaleManually</A>, 172<A href="GXSetIndTexCoordScale.html">GXSetIndTexCoordScale</A> 173</p> 174 175<H2>Revision History</H2> 176<P> 1772006/03/01 Initial version.<br> 178</P> 179 180<hr><p>CONFIDENTIAL</p></body> 181</HTML>
